SharePoint Health Analyzer - Common Issues

I have seen in many SharePoint Farm installations where these messages usually show up in Health Analyzer page. Following are some basic steps that can be taken to get rid of the error/warning messages.

1- The server farm account should not be used for other services.

In the error description, you will see the names of the web application or windows services that is using the service account. Go to Central Administration -> Security -> Configure Service Accounts, Select the proper web application nor windows service and change the service account to an account which is not the system account. If there is no other domain account other than system account, use the Configure managed account page to register a new managed account.

2- Web.config files are not identical on all machines in the farm

Use a file utility like ExamDiff to check for differences in the web.config files. If the web.config files do not match up, make sure that the web.config files are similar across all the servers in the farm. Ensure you take a backup of the web.config files before replacing any files.

Then, you need to turn “off” automatic repair in “Web.config files are not identical on all machines in the farm” rule. This rule can be found in Central Administration -> Monitoring -> Health Analyzer Rule Definition -> under configuration category.

3- InfoPath Forms Services forms cannot be filled out in a Web browser because no State Service connection is configured

You will need to configure the State Service by running the configuration wizard. Detailed information can be found here - http://technet.microsoft.com/en-us/library/ff805084.aspx

4- Drives are running out of free space. 

Hard disk space is low on SP servers mentioned in the warning message. The available disk space should be at least or more than twice the amount of RAM installed on the machine.

Solution 1:  Free disk space on the server computer

1.     Verify that the user account that is performing this procedure is a member of the Administrators group on the local computer.

2.     Run the Disk Cleanup tool to free disk space on the server computer.

Solution 2:   Decrease the number of days to store log files

1.     Verify that the user account that is performing this procedure is a member of the Farm Administrators group.

2.     On the Central Administration Home page, click Monitoring.

3.     On the Monitoring page, in the Reporting section, click Configure diagnostic logging.

4.     On the Diagnostic Logging page, in the Trace Log section, in the Number of days to store log files box, type a smaller number.

5.     Click OK.

Solution 3: Add more disk space on the server

5- Database has large amounts of unused space.

Database files are defragmented or have more storage allocated on disk than actually required.

Follow http://support.microsoft.com/kb/307487/en-us to defragment the databases.
